Step 1: Convert the base-3 number to decimal.
The given number is (210)3.
(210)3 = 2 × 32 + 1 × 31 + 0 × 30
= 18 + 3 + 0 = 21
Step 2: Convert the decimal number to hexadecimal.
Convert 2110 to base 16:
21 = 1 × 16 + 5
Hence, the hexadecimal representation is (15)16.
Final Conclusion:
The hexadecimal equivalent of (210)3 is:
15
Assume that a 12-bit Hamming codeword consisting of 8-bit data and 4 check bits is $d_8 d_7 d_6 d_5 c_8 d_4 d_3 d_2 c_4 d_1 c_2 c_1$, where the data bits and the check bits are given in the following tables. Which one of the following choices gives the correct values of $x$ and $y$? 
If \( x \) and \( y \) are two decimal digits and \( (0.1101)_2 = (0.8xy5)_{10} \), the decimal value of \( x + y \) is \(\underline{\hspace{2cm}}\).
